I have the same issue with the same hardware. I get horizontal black lines flashing on the screen at login, and the screen appears to "twitch" (portions of the screen seem to be randomly flashed, appearing in different locations) whenever I run xrandr or start any programs, like games, that change the resolution.
This never happened with any versions of Ubuntu before Intrepid. -- [intrepid ] screen flickers while loading X, running xrandr or playing a video (i915) https://bugs.launchpad.net/bugs/278146 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
